Why de-normalization required?

Answer Posted / Mohammad Arman Ansari

Degenerating or denormalizing a database is done to simplify data access and improve performance in some scenarios. De-normalization eliminates the need for complex joins, reduces the number of tables accessed during queries, and improves read performance at the expense of write performance and data redundancy. However, it increases the complexity of maintaining the database and can lead to data inconsistencies.
